The median income in Mongaup Valley has fluctuated significantly over the past decade. From 2013 to 2017, there was a substantial increase from $44,324 to $80,023. This period of economic growth coincided with a slight increase in the white population percentage. From 2018 to 2022, there was a sharp decline in median income, settling at $51,112 by 2022. This economic downturn did not significantly alter the racial composition, with the white population percentage remaining above 90%.

Population trends have been volatile, ranging from a low of 246 in 2013 to a high of 512 in 2017, before settling at 417 in 2022. These fluctuations do not appear to correlate strongly with changes in racial composition or median income.

Mongaup Valley's persistent "Low Diversity" status contrasts with national trends towards increasing diversity in many areas of the United States. The economic volatility experienced in this zip code, particularly the sharp rise and fall in median income between 2013 and 2022, may reflect broader economic trends. The stability of the racial composition despite economic fluctuations suggests that this community may have strong cultural or social factors maintaining its demographic profile.

In conclusion, while Mongaup Valley has experienced significant economic changes over the past decade, its racial demographic profile has remained stable, maintaining its status as a "Low Diversity" community. This stability in the face of economic volatility suggests a community with strong ties to its current demographic makeup, potentially resistant to the diversification trends seen in many other parts of the country.
